Hi!
Does anyone know how much current does the signal circuit draw on the ARGB strip that uses WS2815 chip (or WS2813)?
Can Arduino digital pin drive that?
I've tried to search online but all that is coming up are posts about LED power consumption and nothing about signal wires. Does it depend a lot on the chip or most of the time its similar across different strips? As for Arduino output pins according to my research they can provide max of 40mA. https://electronics.stackexchange.com/a/67094
Now a little background for some high level understanding.
I am thinking of building a LED lighting in my living room controlled by the Arduino. Ideally I'd want to chain 4 strips together to make a 20m (60ft) line around the ceiling. I am trying to figure out how I will need to provide data to the ARGB strip from Arduino board and if Arduino will have enough juice for data or I will need some kind of amplifier or repeater or something else.
For now I am looking into following options:
1. Ideally chain all 4 strips together and use single Arduino digital output and connect to data to control all 1200 LEDs.
2. If that will be too much, I am considering connecting two chained strips in parallel and use two separate Arduino data outputs to control each 600 LEDs.
3. If that is still too much, I may have to split it up even more and use 3 or 4 data outputs and control them.
I'd appreciate any pointers.
Thanks
PS: the actual strip I am looking at is this one - https://www.amazon.com/gp/product/B07QGD3YHH

I've also looked at the WS2815 datasheet at http://www.normandled.com/upload/201808/WS2815 LED Datasheet.pdf but a bit confused by characteristics. They list Input Current at 1 µA. Is that the value I am looking for?The absolute maximum for any single IO pin is 40 mA (this is the maximum. You should never actually pull a full 40 mA from a pin. Basically, it's the threshold at which Atmel can no longer guarantee the chip won't be damaged. You should always ensure you're safelybelow this current limit.)
